Abstract
L'invention se rapporte à un procédé et à un appareil pour traiter les chutes de tension instantanées dans l'alimentation d'un équipement à commande numérique par ordinateur, grâce auxquels toute unité d'entrée pour permettre la commutation en position marche/arrêt de la source d'alimentation externe est rendue superflue et l'actionnement des boutons simple. A cet effet, on prévoit dans un équipement à commande numérique par ordinateur (équipement CNC) (3), un circuit d'alimentation (31) qui est connecté à une source d'alimentation externe (1) et qui constitue l'alimentation en courant continu utilisée dans l'équipement CNC (3), un circuit de contrôle de tension (33) qui émet vers une unité centrale de l'équipement CNC une instruction d'interruption destinée à stopper un servosystème, lorsqu'il détecte la chute de tension à la sortie du circuit d'alimentation (31); et un organe (32) générateur de signaux de remise à l'état initial, qui émet un signal de remise à l'état initial vers l'unité centrale, lorsqu'il reçoit de l'organe de contrôle de tension (33) le signal indiquant que l'alimentation a été rétablie après la chute de tension instantanée. Lors du rétablissement après la chute de tension, l'organe (32) bloque l'unité centrale (34) en position de remise à l'état initial pendant un certain temps et débloque ensuite cette unité centrale (34) de cette position pour permettre l'exécution du programme du système. Ensuite, en pressant le bouton de départ de l'unité centrale (34), on peut exécuter une opération programmée.
